Speaking of powdered activated carbon, the first thing that comes to mind is black powdered activated carbon. It is well known that powdered activated carbon is also classified, such as coal-based powdered activated carbon and wood powdered activated carbon, both of which are black powdery in appearance , The difference is not obvious, and powdered activated carbon is generally used for water treatment to remove the peculiar smell, odor and trace elements in the aqueous solution. So the editor is about to start asking questions, which of the coal-based powdered activated carbon and wood powdered activated carbon has the best treatment effect?

So let's take a look at the differences between coal-based powdered activated carbon and wood powdered activated carbon:

1. Coal-based powdered activated carbon uses anthracite as the raw material, which will produce more pore structure during processing. Therefore, coal-based powdered activated carbon is a porous carbon with a relatively developed pore structure with low bulk density and large specific surface area. , It can absorb substances and impurities such as macromolecular pigments in the aqueous solution.

2. Wood powdered activated carbon is made of wood chips, peach shells, fruit shells, etc. as raw materials. The processed activated carbon products are relatively moderate in metal and chemistry, and have a wide range of applications. The application of wood powdered activated carbon is not only It can be used in water treatment as well as in food, sugar, pharmaceuticals, etc. Therefore, the price and demand of wood powdered activated carbon is higher than that of coal-based powdered activated carbon.

3. Because the coal-based powdered activated carbon is made of coal as raw material, it has more impurities and higher chemical composition, and its ash content is slightly higher than that of wood powdered activated carbon, so it does not meet the food specifications. High-quality powdered activated carbon cannot be used in medicine or food. This type of powdered activated carbon is suitable for use in chemical wastewater treatment, industrial wastewater treatment, and domestic sewage treatment.

Through comparison and observation, the editor found that there is no standard for which activated carbon product of coal-based powdered activated carbon or wood-based powdered activated carbon has the best effect. Although on the whole it seems that the performance and use of wood-based powdered activated carbon may be better than that of coal. Powdered activated carbon, but in terms of price and other cost performance, it is better to use coal-based powdered activated carbon.

Although I don't know much about the two powdered activated carbons, I still know through comparison and comparison that there are actually no better activated carbon products, only those that are suitable or not suitable for them. When selecting activated carbon, you must comprehensively consider your own production needs to know whether it is a suitable activated carbon product. In this way, you will get a better treatment effect in the application process and achieve the desired purpose.
